Uninterrupted meter-changing structure of inserted electric energy meter

Abstract

The invention provides a no-shutdown meter changing structure of an insertion-typed electric energy meter, consisting of an electric energy meter and a meter base; wherein, the electric energy meter comprises a meter shell, a plug, a metering mechanism, a flange and an insertion rod; the meter base comprises a base body, a cover plate, a hole-shaped spring, a convex edge, an inlet wire, an outlet wire, an upper spring leaf and a lower spring leaf. After the electric energy meter is inserted into the meter base, the insertion rod passes through a through hole at the upper edge of the upper spring leaf and pushes the upper edge of the lower spring leaf to be open; the power is turned on by the electric energy meter; and after the electric energy meter is pulled out, the power is turned on by the upper spring leaf and the lower spring leaf. The no-shutdown meter changing structure solves the problem that the insertion-typed electric energy meter is changed without turning off the power.

Description

technical field [0001] The invention relates to an electric energy metering device, in particular to a plug-in electric energy meter's continuous power-changing meter structure. Background technique [0002] The existing electric energy meter (also known as electric meter) is installed on the distribution board, and the distribution wiring is exposed to the outside. When disassembling and installing the electric energy meter in this installation method, it is easy to cause wiring errors and cause potential safety hazards. ; Second, it is easy to change the power distribution wiring, so that the current does not pass through or less passes through the energy meter, which affects the accuracy of electricity metering. Now foreign countries have developed plug-in electric energy meters. The wiring is completed by plugs and sockets enclosed in the meter box, which is convenient for safe disassembly and assembly, and can prevent electricity theft. This structure will become the de...
